Sprint announced today it'll offer the submersible Kyocera Hydro Edge beginning on Friday, July 19, and Boost Mobile will offer the device starting Tuesday, July 23, without a contract. Kyocera Hydro Edge, which can be submerged in up to 3.28 feet of water for up to 30 minutes, is part of the new Hydro series of waterproof Android smartphones and builds on the popular Kyocera Hydro, which has been a top seller at Boost Mobile since its launch in August 2012.

Bringing this feature-rich smartphone to both Sprint and Boost Mobile gives customers the choice in how they pay for their devices and their monthly service plans:

Sprint customers will benefit from days at the beach filled with pictures, videos and posts without worrying about overages thanks to Truly Unlimited data, text and calling to any mobile phone with no metering, no throttling, and no overages, all while on the Sprint network. Hydro Edge will be available for just $19.99 (excluding taxes) with a new line or eligible upgrade and two-year service agreement after a $50 mail-in-rebate via reward card in all Sprint retail channels, including Web Sales (www.sprint.com) and Telesales (1-800-SPRINT1).

Boost Mobile customers who choose to pair their device with a no-annual-contract option will benefit from Boost Mobile's $55 Android Monthly Unlimited plan with Shrinking Payments. For every six on-time payments, the cost of Boost Mobile's Monthly Unlimited plan shrinks by $5, eventually getting down as low as $40 a month for unlimited nationwide talk, text and picture messaging, Web, email and calls to 411. Payments do not need to be consecutive to qualify for the next savings milestone. Hydro Edge will be available from Boost Mobile for $149.99 (excluding taxes) at Boost Mobile's exclusive retail stores, select independent wireless dealer locations nationwide and www.boostmobile.com with free shipping. It will be available in early August at select Boost Mobile national retail locations.
